| private boolean | isStemmable(java.lang.String term)Checks if a term could be stemmed.
for ( int c = 0; c < term.length(); c++ ) {
if ( !Character.isLetter( term.charAt( c ) ) )
return false;
}
return true;

| private void | optimize(java.lang.StringBuffer buffer)Does some optimizations on the term. This optimisations are
contextual.
// Additional step for female plurals of professions and inhabitants.
if ( buffer.length() > 5 && buffer.substring( buffer.length() - 5, buffer.length() ).equals( "erin*" ) ) {
buffer.deleteCharAt( buffer.length() -1 );
strip( buffer );
}
// Additional step for irregular plural nouns like "Matrizen -> Matrix".
if ( buffer.charAt( buffer.length() - 1 ) == ( 'z" ) ) {
buffer.setCharAt( buffer.length() - 1, 'x" );

if ( buffer.length() > 4 ) {
for ( int c = 0; c < buffer.length() - 3; c++ ) {
if ( buffer.substring( c, c + 4 ).equals( "gege" ) ) {
buffer.delete( c, c + 2 );
return;
}
